Can I remove black mold myself or need a professional?« Back to Previous Page

The AC in our Jumeirah apartment has been leaking a bit onto the wall behind it, and now we’ve found a big patch of black mold there that’s been growing for who knows how long. We’ve been getting more headaches lately and I’m worried it’s the cause. Is this something I can tackle myself with bleach from the supermarket, or is it absolutely necessary to call in a professional mold remediation company, and what’s the typical cost for a job like this in Dubai?

Based on the description of your situation in Jumeirah, I strongly advise against attempting to remove this mold yourself. A large patch of black mold resulting from a persistent AC leak is a serious contamination issue that requires professional assessment and remediation. The combination of Dubai's high ambient humidity and the constant moisture from the leak creates an ideal environment for extensive microbial growth, often within the wall cavity itself, which you cannot see.

Using supermarket bleach is ineffective and potentially dangerous. Bleach is primarily water, which can feed the mold roots deep within porous materials like drywall. Furthermore, it only bleaches the surface while releasing harmful chlorine fumes, especially dangerous in an enclosed space. Disturbing the mold without proper containment will aerosolize toxic spores, significantly increasing your exposure and potentially spreading the contamination throughout your apartment. Your headaches are a significant red flag and a common symptom of exposure to mycotoxins from certain types of mold.

In Dubai, professional remediation is not just recommended; it is often mandated by building management for health and safety reasons. A certified company like Saniservice will first conduct a thorough inspection to identify the species and the full extent of the growth. The process involves setting up critical containment barriers, using industrial-grade HEPA air scrubbers to filter the air, and safely removing and disposing of contaminated materials like the affected drywall. The cost for a localized remediation job of this nature can vary but often ranges from AED 2,500 to AED 6,000, depending on the extent of the damage and the required repairs.

For your health and to ensure the problem is resolved correctly, you need a professional evaluation immediately. I recommend you call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com for a comprehensive inspection and quote.
